Abstract
In this section of Resonance, we invite readers to pose questions likely to be raised in a classroom situation. We may suggest strategies for dealing with them, or invite responses, or both. “Classroom” is equally a forum for raising broader issues and sharing personal experiences and viewpoints on matters related to teaching and learning science.
The article begins by posing a physics question about a trolley or skateboard placed on stairs and its subsequent motion. The physics behind this problem and some of its extensions are discussed from various approaches.
